fontchart – A font sampler

Pro­duces a font sam­ple that is in some ways sim­pler than that
pro­duced by test­font (in the Plain TeX
dis­tri­bu­tion), but which shows strik­ingly large glyph im­ages,
and avoids some dif­fi­cul­ties with bound­ary char­ac­ters, such as are
of­ten used in Greek fonts (and fonts for sim­i­lar writ­ing sys­tems).
